Is specifying “ATEX” enough?
No. The location classification, required marking and sample conditions must be checked against the proposed configuration.
ABB · Analytical measurement
ABB EL3060 · Hazardous-area gas analysis
Analyser selection considers both the surrounding atmosphere and the gas passing through the system.
Architecture for hazardous areas
EL3060 uses flameproof enclosures. The control unit can contain a Magnos28 oxygen module or a Caldos25/27 thermal conductivity module; the Uras26 photometer has a separate enclosure.
ABB offers Zone 1, category 2G versions with ATEX/IECEx certification. Select the supply against the marking and certificates for the actual configuration.
Two separate checks
| Check | Required information |
|---|---|
| Installation environment | Zone, gas group, temperature class, ambient temperature and site requirements. |
| Sample inside the instrument | Composition, flammability, oxygen, pressure and anticipated abnormal conditions. |
Cabinet integration
The assessment covers the whole path: sampling, tubing, fittings, pumps, valves, vents and supplies. A certified enclosure does not automatically make the other system components suitable.
Allow maintenance access, connection space and identification of sample and calibration lines. Unit positioning must permit maintenance in accordance with ABB instructions.
ABB documentation
Information for a quotation
To select EL3060, send us the following information, even if preliminary:
- Components to be measured, background gas and expected interferents.
- Normal, minimum and maximum ranges; units and dry or wet basis.
- Pressure and temperature at the sampling point; moisture, dust and condensable components.
- Required response time, number of points and distance from the sampling point.
- Area classification, indoor/outdoor installation, available signals and utilities.
- Area classification and project Ex specification; composition under start-up and fault conditions as well as normal operation.
Frequently asked questions
Does EL3060 automatically replace EL3040?
No. Architecture, available modules, installation and permitted conditions must be compared for the project.
